At the recession bottom on March 9th, 2009, just nine and a half years ago, the S&P 500 was at 683. Investors that bought and held over this period increased their investment value by over four times. The C Fund, of course, is the TSP fund that tracks it.

And this doesn’t even account for dividends. With dividends reinvested (which the C Fund does automatically), the total return was about 5.25 times the original investment. The C Fund went from less than $8/share to over $41/share during this time.
